Best option for selling a non-drivable car

@Triedaq is right. The only other suggestion I have is that you MIGHT find a good used transmission at www.car-part.com, but consider that many of those in ten year old wrecked/salvage cars will have as many miles on them as yours has. If you buy a used one, be sure they give you a good warranty on it. Some will give up to six months, but most are 30 days or 1000 miles, whichever comes first. Get one with a six month warranty, and then start looking for a new car.
